PAPJIEJEPFASTENJEHRJ- Specification of Letters Patent.

application filed July 1-917. iterial lilo. l79,ltitt b all whom it may concern:

Be it known that we, JAMns Ron brarronn and FRED J. KLEIN, citizens of the United States, and residents, respectively, of Uregon tity, in the county of Clackamas and State of tlrcgon, and the city, county, and State of New York, have invented certain new and useful Improvements in Paper-Fasteners, of which the following is a specification.

This invention relates to paper fasteners andparticularly to tongued paper fasteners which are used with retaining members or washers having slots through which the tongues can be passed after .being pushed through papers and having means for holding down the ends of the tongues after these are pushed through the papers and the retaining members and bent fiat on the latter.

The main object of the invention is to provide a fastener which has positive means for locking the ends of the tongues in position in said holding means when the fastener are in use holding papers.

in the accompanying drawing we have shown embodiments of paper fasteners and retaining members or washers, which are illustrative of our improvements, and in which,

Figure 1 is a perspective view of a paper fastener and its retaining member embodying our improvements, and also showing the dotted outline of a portion of a file of papers P.

Fig. 2 is a plan of the left hand portion of the fastener and retaining member of Fig. i.

Fig. 3 is a transverse section on the line a s of Fig. 2.

Figs. 4 and 5 are details of portions of the fastener tongues of Figs. 1, 2 and 3.

Figs. 6 and 7 are respectively, plan and side elevation of another embodiment of our Invention. Figs. 8 and 9 are details of the fastener tongues of Figs. 6 and 7.

Similar characters refer to like parts in all figures of the drawings.

The tongued members for use with curinvention may be of any suitable form, but in the various figures of the drawings, where they are designated generally by the letter F, they consist of a rectangular base 2, having ridges or corrugations 2 for stiffening the base, and two tongues 3, one at each end thereof.

The retaining member or washer t is also preferably of rectangular form and provided with ridges or corrugations 7. Transverse slots 6 are formed near each end, preferably between the ridges, and through which the tongues 3 can be-passed after they are putthrough a tile of papers.

Hold ng means for the tonguesare formed in the retaining members, and are preferably In the ridges or corrugations thereof. The form we prefer to use eonsistsof longitudinal edges formed by slotting the ridges or corrugations as at 8. These actto hold the tongues 3 when the latter have been pushed through a file of papers and the retamlng member, then bent down flat on the latter and pushed laterally into the slots 8 under the said longitudinal edges.

t)ur improvements provide for more emcient means for securing the tongues in the holding means than the means heretofore used, and their main advantage is to prevent the ends of the tongues from working loose and catching on neighboring objects.

lteferringto Figs. 4 and 5, we illustrate here the locking means of this embodiment of our invention. These comprise a downwardly projecting lug or projection 11 at the end of each tongue 3, and divided from the other part of the tongue end by a cut 12. The lug should not be bent down until the tongue has first been passed through the papers and transverse slots, after whichit is bent as shown, and the tongue is then bent down flat on the face of the retaining member. When the end of the tongue is bent laterally under the holding edges 13 of the longitudinal perforations 8, the lug ll slips into the perforation and holds the lid Tfti

end of the tongue fast, and will not worlr loose unless pried up with a special tool.

in the form of our invention shown in Figs. 6 to 9 inclusive, the tongue 3 is pro-- vided with a lu or projection it at some distance from tie end of the tongue. in securing the tongues, the tongue 3 is given the lateral movement before the other tongue 3 is moved, and when the latter has been moved laterally, it comes on top of the tongue 3. in other words the tongues must overlap in using this form of the in vention. The lug or projection la is then bent u a as shown in Figs. and ti, and acts to loclr the tongue 3 from moving baclr from under the holding edge 13. The

tilt

lltl ti tongues can not now Work loose until the. lug 14 is bent. down again to unlock them.

What We claim is 1. In a paper fastener, the combination With a retaining member having tWo transverse slots and tongueeholding and shielding means, and a member having two tongues adapted to be passed through papers and said transverse slots, bent flat on the retaining member held down by the tongue-holding and shielding means, 'of means for positively lockin the tongues in position in the tongue-hol ing and shielding means.

2. In a paper fastener, the combination with a member having tWo transverse slots and tongue-holding means and a member having 'tWo tongues adapted to be passed through papers and said transverse slots, bent flat on the retaining member and held by the tongue-holding means, of a lug embodied in one of said tongues for positively looking it in position in the tongue-holding means.

In a paper fastener, the combination With a retaining member having two transverse slots and two longitudinal tongueholding edges, and a member having two tongues adapted to be passed through papers and sa d transverse slots, bent Hat on the retaining member, and held under the tongue-holdin edges, of a downwardly extending lug in the end of each tongue which is adapted to engage a tongue holding edge of the retaining member.
